“…Numerous trials have established buprenorphine’s utility in the treatment of opioid dependence (Johnson et al, 1995; Johnson et al, 2000; Amass et al, 2004; Ling et al, 2005), and its use in substance abuse treatment has been rapidly increasing (DEA, 2011, February; Yokell et al, 2011). Although years of clinical research and post-marketing data show that buprenorphine misuse carries lower risk of serious side effects compared to other opioids (Bridge et al, 2003), cases of buprenorphine abuse and related morbidity and mortality (including adverse events linked to injection and unintentional overdoses) have been documented in many countries around the world (Chowdhury and Chowdhury, 1990; Tracqui et al, 1998a; Tracqui et al, 1998b; Agar et al, 2001; Vidal-Trecan et al, 2003; Jenkinson et al, 2005; Schifano et al, 2005; Parfitt, 2006; Bruce et al, 2008; Yokell et al, 2011). There is growing evidence that these products are being diverted in the U.S. (Cicero et al, 2007; Smith et al, 2007; Dasgupta et al, 2010; Maxwell and McCance-Katz, 2010; Johanson et al, 2011).…”
